Question

state and prove parallelogram have of vector addition and also give iys analytical treatment.​

Answer 1

Explanation:

The parallelogram law gives the rule for vector addition of vectors and . The sum of the vectors is obtained by placing them head to tail and drawing the vector from the free tail to the free head. Let denote the norm of a quantity. Then the quantities and are said to satisfy the parallelogram law if.

Parallelogram law, like triangle law, is applicable to two vectors. If two vectors are represented by two adjacent sides of a parallelogram, then the diagonal of parallelogram through the common point represents the sum of the two vectors in both magnitude and direction.
